What file sizes are you talking about?
The question typically isn't large file support in Oracle Linux (OL), but rather a question of the zip/unzip utility. UnZip's random-access operation and (partial) dependence on the stored compressed-size values limits the total size to something in the neighborhood of 2 to 4 GB.
See the following link: http://www.info-zip.org/FAQ.html#limits
OL ships with unzip version 5.52.
if you want to archive zip files I suggest to use the tar utility, for instance: tar cvf myfile.tar *.zip
Correction: This is occurring on a 5.7 release and not a 5.8. The command uname -a yields 2.6.32-188.8.131.52...
The file size I'm trying to assemble is ~ 4 GB (the zip files for 12c DB). As for using tar, as I understand it, EM 12c wants a single zip file for software deployments.
I'm assuming that the large file support was not linked into the utilities. For example when I try to list contents of a directory which has huge/large files, I get the following message:
ls: V29653-01.iso: Value too large for defined data type
I'm assuming that I need to upgrade to later release.
The kernel version does not necessarily explain the Linux release version. Are you sure you are using a x86_64 kernel? Large file support, from what I understand means 64-bit support. Perhaps you are using a 32-bit (i686) system.
